[pablomendezroyo]

Join BSON by network tag and pubkey and update the new entries in the same BSON.

filter := bson.M{
    "tag":      req.Tag,
    "network":  req.Network,
    "pubkey":   req.Pubkey,
}

update := bson.M{
    "$push": bson.M{
        "entries": bson.M{
            "payload": req.DecodedPayload.Payload,
            "signature": req.Signature,
        },
    },
}

options := options.Update().SetUpsert(true)

_, err := dbCollection.UpdateOne(context.TODO(), filter, update, options)
if err != nil {
    // Handle error
}

Do not store in db decoded payload
